Description
Technical field
The present invention relates to a kind of fisher of drilling failure, belong to novel compound fishing tool.
Background technology
The fishing tool of drilling failure is a lot, but every fishing tool all has its scope of application, i.e. limitation is when handling in the well accident; Should be according to the situation in the well, and adopt different processing methods and fishing tool, the fishing tool that has can directly be bought; The need field machining that has has disposablely during use, situation is special in the well sometimes; Perhaps complicated, can only drilling well be done and scrap processing, the economic cost of paying is quite heavy.
Block, bury, burn, glue etc. that drilling tool accident is that drilling tool common in the drilling failure is lost into accident in the well in the well, handle the method that adopts often to be:
1) promotes: in the safe range of equipment, handle, but often new accident is led to because of misoperation in the scene, and equipment is also had certain damage.
2) strengthen circulation: prerequisite is to set up circulation, often in mud, adds different mud materialses.
The emergency processing measure of taking when more than just accident takes place.
3) oiling (or decoder): be used for exploring deep-well, prerequisite is to set up circulation more, needs to inject a large amount of oils such as diesel oil, and processing cost is higher untimely with processing.
4) explosion is become less severe: when above method is invalid; The exploration deep-well is used for explosion more and becomes less severe, and needs to engage the explosion of the specialty troop of becoming less severe, after explosion is become less severe; Often bottom part drilling rod, drill collar or coring tube are lost in the well; Can't salvage, can only cement the shut-in well sidetracking, cause processing cost higher with handle untimely.
5) adopt anti-silk drilling tool anti-: when above method was invalid, it is anti-that the exploration shallow well is used in anti-drilling tool more, and the exploration deep-well does not often adopt, and reason is: the anti-silk of lease drilling tool cost is too high; Contact, the anti-silk of transportation drilling tool need the time, have lost the Best Times of processing accident; The board space is little, and anti-silk drilling tool is put difficulty with the positive silk drilling tool that salvages.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of counter-rotating dart, and it is simple in structure, and use cost is low.Do not receive the shallow restriction of well depth and well.
The present invention solves the technical scheme that its technical problem takes: there is external tooth the lower end of upper gear mandrel; Described upper gear mandrel is with overcoat outward, in the cannelure between upper gear mandrel and the last overcoat last sealing ring and up-thrust bearing is arranged, and the upper end of last sealing ring compresses through upper press cover; Upper press cover is connected with the described sleeve thread of going up; There is the stressed pressure ring of going up on top, the lower end of said up-thrust bearing, and there is middle overcoat on the top, lower end of going up stressed pressure ring and said upper gear mandrel, is fixed on described China and foreign countries with the idler gear of the external tooth engagement of said upper gear mandrel through the taper wear-resistant sleeve and puts; The internal tooth that meshes with said idler gear on the upper end inner cylinder face of undergear mandrel; There is following overcoat on top, the lower end of overcoat in said, in the cannelure between following overcoat and the described undergear mandrel lower thrust-bearing is arranged, and lower thrust-bearing is compressed by the lower stress pressure ring; The lower stress pressure ring is connected with described undergear mandrel thread; The top, lower end of said overcoat down has end overcoat, lower cover to compress end overcoat through lower seal, and lower cover is connected with end sleeve thread.
The present invention's drilling tool that only need reverse just equals to have had the anti-silk of cover drilling tool, and, do not receive the shallow restriction of well depth and well.Overcome the shortcoming that anti-silk drilling tool hiring cost is high, non-cutting time is many, lost the Best Times of processing accident.Simple in structure, use cost is low.Use rig can realize salvage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Accompanying drawing is a half sectional view of the present invention.
The specific embodiment
Shown in accompanying drawing, there is external tooth the lower end of upper gear mandrel 1.Be with overcoat 4 outside the described upper gear mandrel 1, last sealing ring 3 and up-thrust bearing 5 are arranged in the cannelure between upper gear mandrel 1 and the last overcoat 4, the upper end of last sealing ring 3 compresses through upper press cover 2, and upper press cover 2 is threaded with the described overcoat 4 of going up.There is the stressed pressure ring 8 of going up on the top, lower end of said up-thrust bearing 5, and there is middle overcoat 11 on the top, lower end of going up stressed pressure ring 8 and said upper gear mandrel 1.With the idler gear 9 of the external tooth of said upper gear mandrel 1 engagement through taper wear-resistant sleeve 10 be fixed on described on the overcoat 11.The internal tooth that meshes with said idler gear 9 on the upper end inner cylinder face of undergear mandrel 12.There is following overcoat 14 on top, the lower end of overcoat 11 in said; In the cannelure between following overcoat 14 and the described undergear mandrel 12 lower thrust-bearing 13 is arranged; Lower thrust-bearing 13 is compressed by lower stress pressure ring 16, and lower stress pressure ring 16 is threaded with described undergear mandrel 12.The top, lower end of said overcoat 14 down has end overcoat 17, lower cover 19 to compress end overcoat 17 through lower seal 18, and lower cover 19 is threaded with end overcoat 17.
